This paper is the eye region which is used with confirmation element of face image it uses the SIFT and it extracting method proposes. The eye region image where becomes model and it composes the keypoint descriptor which is a SIFT result of the input image which it will extract. It uses the keypoint descriptor which and creates it composes a each feature vector, and the judgement where affine transform should have existed on after two feature points which adjusts with each other, against the feature point field which confront above half as the case eye region where the with each other same affine transform will exist it judged. There is not a test result learning process, more quickly recognition method of existing methods than the possibility of getting the result which extracts the region it was.

MPEG-4 for an object base coding after extracting the region from image, the coding for a real-time requirements is quick and must be accurate. The object crisis algorithms of existing calculation quantity are many and with image transformation or video conferencing system to same real-time application they are not suitably. The object real-time tracking it tried to apply the CAM-Shift algorithm which is possible from the dissertation which it sees consequently. Tracking the object which it moves or wants the VO where (Video Object) tracking the user wants in bounding box form defines the object where is started. Tracking the object of after uses a CAM-Shift algorithm and are extracted and the VOP with the VO which it is composed. It defines one bounding box with the method which is proposed consequently about lower only one VOP there to be it will be able to compose, it becomes.

Purpose : To investigate the shape and size of normal sella turcica on cephalometric radiograms. Materials and Methods : Cephalometric radiograms of 200 orthodontic patients of age ranging 6-42 years were examined. All subjects were divided into 5 groups by age, the dimensional change of sella turcica was examined according to age, and the configurations of sella turcica floor, tuberculum sella, and anterior and posterior clinoid process were also observed. Results : The contours of sella turcica floor were flat type in 54% and concave type in 46%. The contours of tuberculum sella were right angle type in 55% and obtuse angle type in 44%; Acute angle type and plane type were very rare comprising 0.5%, 0.5% each. The configurations of anterior clinoid process were point type in 80% and round type In 20% of cases, and those of posterior clinoid processes were point type in 60% and round type in 40% of cases. The dimensional change of sella turcica according to age range had significantly positive linear trend to sella turcica length, height, and width until 25 years. After 26 years, no significant increase was found in sella turcica dimension. Especially, the sella turcica length had more proportional increase than that of sella turcica height and width. Conclusion : The results of this study revealed that the configuration of normal sella turcica was variable and the dimensional change of normal sella turcica had a linear tendency with age until 26 years.(Korean J Oral Maxillofac Radiol 2001;31:43-9)

The DNA fingerprinting for individual identification using legal medical evidence has been recognized to be one of the most excellent and usable methods. Therefore, an experiment was performed to verify the possibility of obtaining DNA fingerprints from a bloodstain, and to examine the effects of the common environmental conditions, such as the type of materials which the bloodstains have dried on relative humidity (65% and 98%), ultraviolet rays, infrared rays and temperature, on the DNA fingerprinting using bloodstains prepared in the laboratory. The following results have been achieved: 1. A high molecular weight DNA was able to be extracted from the bloodstain prepared for this experiment, and was possible to be used for individual identification upto a certain period of time. 2. Extraction of high molecular weight DNA in bloodstains which were formed on cotton, leather, wood, glass plate, and stainless steel was not likely to be any different. 3. The extracted DNA was easily affected by the variations in temperature, but humidity, ultraviolet and infrared rays did not have any significant effects.

The osteochondroma, also known as osteocartilagenous exostosis, is one of the most common benign tumors of the axial skeleton, but is rarely found in the facial bones. When present, the tumor is most often reported to affect the mandibular coronoid process. Osteochondroma of the mandibular condyle is extremely rare and may cause signs and symptoms like those seen in patients with temporomandibular joint dysfunction. Sometimes, differentiation between osteochondroma and condylar hyperplasia is not possible on histologic grounds alone, but the radiographic and intraoperative findings together are usually sufficient to establish a definite diagnosis, This report reviews the literature concerning osteochondroma, especially of the maxillofacial region, and describes a case of osteochon droma of the condyle.

After Liberation of the Korean Peninsula, August 15, 1945, the United States and the Soviet Union Armed Forces were stationed on the North and the South Korea being the boundary line of the 38th Parallel. For the solution of this Korean problems, the United States and Soviet Union offered proposals of Trusteeship. Because the failure of the agreement between the U.S. and the Soviet Union in trusteeship consensus, the 38th parallel was constructed the real wall. As the greatest matter of the Korean people the time was the building of the Unified Nation States, that matters required the international cooperation, reopening the Joint Commission. They required the wide gathering of the inter-nation political leaders and groups so that the Joint Commission reopened, this mission was operated the Right and Left wing coalition Movement groups. The purpose of the Coalition Movement was the the building of the Unified Nation States in Korea, through the consensus of the international political groups and leaders. This Study focuses on the process of the Coalition Movement after liberation in Korea. The process of the Coalition Movement was, the first step(1946.5-1946.10): Starting of the Coalition Movement and consensus of the coalition principles, the second step(1946.10-1946.12):Opening of Korea-U.S. Common Conference(the agenda-the pending bills of the time) and establishment of the Interim Legislative Assembly of the south Korea under the USAMGIK, the third step(1947.1-1947. 12: Reopening and rupture of the second Joint Commission and disassembling of the Coalition Committee. The Coalition Movement ended in failure on account of the negative attitudes and the disturbances of the extreme rights and the extreme lefts, but the Coalition Movement is still the historical manifestation in that the Korean Peninsula has continued the 38th parallel during 50 years, therefore this movement get a lot of suggestions in the Reunification of Korea.

This study has an object of searching for appropriateness in applying the trip distribution model by studying the changes of the character of parameter which the model contains and by analyzing and evaluating trip distribution technique out of four steps of pre-estimate technique for the traffic demand through computer simulation centering around Kwangju. Method of this study is investigating the basic theory for trip distribution model and with this grounding, I rearranged it as research data for trip distribution model compatible for Kwangju, using data such as research data on actual state, the statistics annual report and basic plan for traffic full equipment of Kwangju. So, The most stable measure of the type of trip distribution of Kwangju city was produced in Fratar and Detroit model, however, gravity model has a little bit low reliance in sharing of estimation and actual survey although it is astringent in short period.
